The Construction Of The Evaluation Model In The Research And Development For The Disabled Based On The D-S Evidence Theory

Sports equipment is one of the hardwares in sports, which is regardedas the material guarantee. Therefore, reasonable research anddevelopment of the sports equipment is an important factor to increasethe quality of sports and level of athletics in our country. On theresearch methods of sports equipment, the procedures of equipment R&D aresimilar no matter for the abled and the disabled, or the competitive sportsand the popular sports. Equipment R&D is divided into two steps---productshaping and product improvement,in which “evaluation process” runsthrough them and plays a key role in the success of the new equipment R&D.This research brings the D-S theory founded by Dempster and Shafer intothe sports equipment R&D and discusses the problem of group decision andproof fusion in the procedure of sports equipment R&D. This paper adoptsthe analytical method of D-S evidence theory to evaluate home-madeprompters that is remote control and luminous for the deaf in thebasketball match. We try to offer a new idea and method of sports equipmentR&D for our country. Moreover, the home-made luminous reminders in thisresearch can help the deaf athletes receive prompt messages in time ina tight game. We hope to improve the performance of reminders throughexperimental researches and try our best to solve the troubles deaf peoplehave in basketball matches.The major research contents:（1）The author chooses related and important concepts and formulas andsums up each kind of calculating method and its advantages anddisadvantages, and then choose a right synthesis algorithm for thisresearch. By using a simple calculation example, we apply the D-S evidencetheory in sports equipment R&D.（2）Because of the hearing limit in the deaf basketball matches,suspension signals could not passed to athletes, which leads tounnecessary energy wasting of referees. Due to the above reasons, wedesigned this prompter that could glow with remote control and is easyto carry on athletes to replace the traditional method of waving colorfulflags that suspends the game quickly and effectively. （3）Through the analysis of visual diversity, we found no obviousdifferences between the deaf person and normal person and the vision sizesof different colors are sorted as:”yellow＞red＞green”. Thisexperimental result helps not only avoid invalid data caused by unusualview, but also provide theory basis of choosing the right color of LEDon the reminders.（4）Through10matches played, we compared the difference of competitiontime and judgement time by using the homo-made reminder and colored flags.The result shows that there is no obvious difference caused by frequencyof violations and fouls by using two methods in game time (gross time).However, there is notable difference on judgement time--the time of usingreminder is makeable shorter than that of using flags.（5）The author of this paper establishes the team of group decision andthe evaluation system of the home-made, remote control and luminousreminders by using the method of D-S evidence theory. We get experts’advices after interviewing them, and synthetically calculate byquantifying those advices and using the assembly mode. Finally, the authorachieves the evaluation of the reminders. We approves by research thatsynthetical calculation in D-S theory is not only superior to traditionalexpert weighting method, but also easier than Eigenvalue Method, FMEA,AHP.The author uses the same calculation method to finish the syntheticof group decision information and use statistical software to edit andcalculate formula on data processing, which make the whole processrelatively more efficient.
